Abstract (en)

The present invention pertains to a two-component mortar system for chemical fastening of anchoring means in mineral substrates, comprising a curable aqueous-phase aluminous cement component A and an initiator component B in aqueous-phase for initiating the curing process, component A further comprising at least one blocking agent selected from the group consisting of boric acid, phosphoric acid, metaphosphoric acid, phosphorous acid and phosphonic acids, and water, and component B comprising blocked ground-granulated blast-furnace slag, water and optionally at least one mineral filler. Moreover, the present invention pertains to a two-component system, which is ready-for-use, for chemical fastening of anchoring means, preferably of metal elements, in mineral substrates, such as structures made of brickwork, concrete, pervious concrete or natural stone as well as its use for chemical fastening of anchoring means.
